It is 1/2.

The probability of 2 coins both landing on heads or both landing on tails is 1/2 because there are 4 possible outcomes. Head, head. Head, tails. Tails, tails. Tails, heads. Tails, heads is different from heads, tails for reasons I am unsure of.

Coins do not have numbers, there is only the probability of heads or tails.

It is 1/2.

10/32 = 5/16

It is 0.5

The probability of flipping three tails with three coins is (1 in 2)3 or 1 in 8 or 0.125.

The side heads is slightly heavier giving it a greater likely hood of landing on tails.

Because you are thinking permutations rather than combinations. There are four permutations of two coins, but there are only three combinations, because it does not matter which coin is heads and which coin is tails. As a result, the combination of heads and tails has a 0.5 probability, while two heads or two tails each have a 0.25 probability.

Coins do not have numbers, there is only the probability of heads or tails.

The probabilty of you flipping 3 coins and getting all heads or tails is 0.125 or 1/8.

It is 1/2.

10/32 = 5/16

The probability of getting all heads is 1/24 = 1/16 The probability of getting all tails is also 1/24 = 1/16 The probability of all heads or all tails is the sum of the two = 1/8

lets get some facts odds of head on 1 coin 50% or evens odds of no head 50% or evens the possible results vary from 1 coin to 2 coins. 1 coin has 2 results heads or tails 2 coins have 4 results. heads heads, tails tails, tails heads, heads tails. each outcome has a probability of 25%. for the question we remove the heads and tail probability and we have 2 outcomes with heads and one without. so 2 to 1 chance or 33.3333 recuring chance.
